The T10 is Lamy’s proprietary fountain pen refill. These cartridges has bean Lamy’s design for over 30 years and work with almost all Lamy pens, aside from the Lamy 2000. It has a 1.15 ml capacity and is made out of a hard plastic.
The T10 cartridge is generally sold in 5-packs, with the common colors being black, blue, dark blue, red, green, turquoise, and purple. Special editions colors are sometimes made and are sold in limited quantities. The 2019 special edition color is bronze.
All Lamy fountain pens aside from the Lamy 2000 are cartridge converter that will accept this cartridge or one of the brand’s converters (the Z24, Z26, Z27, and Z28 are the most current models). Choosing a Lamy fountain pen converter can be be confusing, but finding a cartridge is not because the T10 is the only cartridge that Lamy makes. This includes the popular Lamy Safari, Al-Star, Lx, and Vista in the entry-level and extends up to the Lamy Imporium, Scala, Dialog 3 and other premium, gold nib fountain pens.
The 1.15 ml capacity puts these cartridges at a very good size compared to a typical fountain pen converter. The Z28, the current converter for the Lamy Safari, has a capacity of just 0.8 ml, which is about a third less ink than the T10.
The T10 is made of hard plastic that is refillable with a fountain pen syringe. This is not a behavior that is recommended by Lamy but it’s a good way to use affordable Lamy fountain pen ink with cartridges, which are comparatively much more expensive when view on a per-milliliter basis. A Lamy 50 ml ink bottle (known as the T52) will currently sell for about $12 where a 5-pack of cartridges will sell for $4.50, both through an authorized deal in the United States. This puts the pricing as follows:
- T52 ink bottle: $0.24 per ml
- T10 cartridge: $0.78 per ml
That means that the T10’s ink is about three times more than that from a bottle, which makes a fountain pen converter well worth it, but Lamy’s cartridges have proven themselves to be reliable, leak-resistant, and high performance. As a result of these qualities, it’s not uncommon for long-time and frequent Lamy fountain pen fans to stick with the T10.
